要生成脚手架:

rails generate scaffold abc

恢复脚手架:

rails destroy scaffold abc

如果您已经为它运行了迁移，只需回滚即可

rake db:rollback STEP=1

你也需要在摧毁脚手架后回滚迁移

rails destroy scaffold 'scaffoldname'
rake db:rollback

要生成脚手架:

rails generate scaffold abc

恢复脚手架:

rails destroy scaffold abc

如果您已经为它运行了迁移，只需回滚即可

rake db:rollback STEP=1

Rishav Rastogi是对的，rails 3.0或更高版本:

rails generate scaffold ...

rails destroy scaffold ...

用于在轨道中生成脚手架

rails generate scaffold MODEL_GOES_HERE

用于在轨道上撤消脚手架-

rails destroy scaffold MODEL_GOES_HERE

要生成脚手架:

rails generate scaffold xyz

恢复脚手架:

rails destroy scaffold xyz
